A pinch valve is a valve that controls the movement of fluid by squeezing a hose. The squeezing action can be achieved through a mechanical mechanism and can be driven by pneumatic, electric, manual, or electromagnetic force. Unlike traditional valves, pinch valve components do not contact the medium, only require certification requirements for tubing fittings, and have extremely low pressure drop, making them widely used in fluid control applications (e.g. analytical chemistry, in vitro diagnostics, environmental monitoring, and liquid phase analysis, and bioengineering, food and beverage industry).
